Preface

Oracle Spatial Topology and Network Data Models provides usage and reference information about the topology data model and network data model of Oracle Spatial, which is often referred to as just Spatial.

This preface contains these topics:

• Audience

• Documentation Accessibility

• Organization

• Related Documentation

• Conventions

Audience

This guide is intended for those who need to use the Spatial topology or network data model to work with data about nodes, edges, and faces in a topology or nodes, links, and paths in a network.

You are assumed to be familiar with the main Spatial concepts, data types, and operations, as documented in Oracle Spatial User's Guide and Reference.

Documentation Accessibility

Our goal is to make Oracle products, services, and supporting documentation accessible, with good usability, to the disabled community. To that end, our documentation includes features that make information available to users of assistive technology. This documentation is available in HTML format, and contains markup to facilitate access by the disabled community. Accessibility standards will continue to evolve over time, and Oracle is actively engaged with other market-leading technology vendors to address technical obstacles so that our documentation can be accessible to all of our customers.

Accessibility of Code Examples in Documentation

Screen readers may not always correctly read the code examples in this document. The conventions for writing code require that closing braces should appear on an otherwise empty line; however, some screen readers may not always read a line of text that consists solely of a bracket or brace.

Accessibility of Links to External Web Sites in Documentation

This documentation may contain links to Web sites of other companies or organizations that Oracle does not own or control. Oracle neither evaluates nor makes any representations regarding the accessibility of these Web sites.

Organization

This guide has two main parts. The first part contains conceptual, usage, and reference information about the topology data model of Oracle Spatial. The second part contains conceptual, usage, and reference information about the network data model of Oracle Spatial. If you develop network applications, you must understand the main concepts in both parts.This guide has the following elements.

Part I, "Topology Data Model"

Contains chapters with conceptual, usage, and reference information about the topology data model of Oracle Spatial.

Chapter 1, "Topology Data Model Overview"

Provides conceptual and usage information about the topology data model.

Chapter 2, "Editing Topologies"

Explains how to edit node and edge data in a topology. The operations include adding, moving, and removing nodes and edges.

Chapter 3, "SDO_TOPO Package Subprograms"

Provides reference information about functions and procedures in the PL/SQL package MDSYS.SDO_TOPO.

Chapter 4, "SDO_TOPO_MAP Package Subprograms"

Provides reference information about functions and procedures in the PL/SQL package MDSYS.SDO_TOPO_MAP.

Part II, "Network Data Model"

Contains chapters with conceptual, usage, and reference information about the network data model of Oracle Spatial.

Chapter 5, "Network Data Model Overview"

Provides conceptual and usage information about the network data model.

Chapter 6, "SDO_NET Package Subprograms"

Provides reference information about functions and procedures in the PL/SQL package MDSYS.SDO_NET.

Chapter 7, "SDO_NET_MEM Package Subprograms"

Provides reference information about functions and procedures in the PL/SQL package MDSYS.SDO_NET_MEM.

Oracle error message documentation is only available in HTML. If you only have access to the Oracle Documentation CD, you can browse the error messages by range. Once you find the specific range, use your browser's "find in page" feature to locate the specific message. When connected to the Internet, you can search for a specific error message using the error message search feature of the Oracle online documentation.
